How did the artificial selection practiced by pigeon breeders influence Darwin's theory of evolution by natural selection? A. Darwin concluded that if breeders could select for certain traits in pigeons, they could also select for certain traits in saddleback tortoises. B. Darwin concluded that if traits in captive pigeons could be selectively passed on to offspring, the selection of traits could also happen in nature. C. Darwin concluded that if pigeons could choose their own traits, then animals in the wild could also choose their own traits. D. Darwin concluded that if artificial selection could change a population over time, it could change a population instantly as well.

i think that d. wind is the answer.   i missed the question when i answered a. currents.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

a scenario where a cell may be needed to perform a form of endocytosis is when transporting large molecules. a scenario where a cell may be needed to perform a form of exocytosis is when releasing the large molecule from the cell.
